To (tZZ whom, it may concern: 1

Be it known that I, OURTIs HUSSEY Ven- DER, a citizen of theUnited States, residing in the city of Hartford, county of Hartford, State 5 of Connecticut, have'invented certain new and useful Improvements in Machines for Cutting Off Metal Rods, &c., of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

It is well known that when wire, rods, or bars of metal are cut off or sheared off by the ordinary methods there is likely to be more or less distortion of the ends of the wire, rod, rg or bar adjacent to the cut and that some: times a fin or bur is left. When thewire; rod, or bar is used in longlengths, the amount of labor necessary to restore the ends to their proper shape or'to remove the fins or burs nary methods of cutting or shearing can be employed; but when the wire, rod, or bar is to be used in many short lengths the value of the labor necessary to restore or finish the ends bears an unduly large ratio to the value of the finished part.

, It is therefore the object of this inventionto produce a machine which shall be capable of cutting ofi wire, rods, or bars either of cy- 0 lindrical or other crosssection without ma terially distorting the ends and without leaving any fin or bur and of operating with great rapidity. Obviously a single out in one direction only is liable to produce excess- 3 ive distortion, and the present machine is therefore so organized as. to cut or shear progressively from different points about the wire, rod, or bar to be out. As thus organized the machine comprises two cooperating 4o bushings arranged and formed to have a shearing action upon the wire, rod, or bar to be out which is passed through them, the one of said bushings having a rolling motion of, progressively-increasing eccentricity with respect to the other bushing, such bushings preferably having'no movement of rotation with respect to the wire, rod, or bar to be out other than the rollingaction referred to. As will appear more clearly hereinafter, the

bushings may have an actual movement of Serial No. 161,956. (Na model.)

i not rotate about its own axis.

The invention finds expression in its simplest mechanical form when the wire, rod, or bar and the bushings rotate at the same angular speed about the axis of the wire, rod, or bar; but in' some cases it is impracticable when handling the wire, rod, or' bar in long lengths to let it rotate about its own axis, and in such cases the bushings are held from rotationabout their axes, having only the relative rolling movement necessary to secure the progressive shearing action.

In the'accompanying drawings both em- ,bodimentsof the invention are illustrated for the purpose of enabling the nature of the :invention to be understood. v

In said drawings, Figure 1 is a view in side elevation of a machine operating in accord ance with the invention, the cooperating bushings having no movement of rotation 7 5 about their own axes. Fig. 2 is a view in verticai' central section. Figs. 3 and 4 are respectively a front elevation with the operating-handle insection and a top plan view of the same. Figs. 5, 6, and 7 are respectively So a plan view,a-longitudinalsection on the plane indicated by the line 6 6 of Fig. 5, and an end elevation of an embodiment of the invention in which the bushings are adapted to rotate with the wire, rod, or bar to be out.

In the machine shown in Figs. 1, 2, 3, and e the two parts which by their cooperation progressively shear the wire, rod, or bar and for convenience are called bushings, al-

though, as will be obvious, they might have groove 1' in the shaft.

To this end it is threaded in a block (2 and'is secured therein by a set-screw d, the block 6 being mounted in gimbals. The block e is directly supported by pivot-screws e in a frame f, which in turn is supported by pivotscrews f at right angles to the pivot-screws e between suitable brackets c at the head of the standard 0. The block e is provided with an arm e which is extended downwardly through an opening 19' in the arm I) and is turned at right angles to engage a pin g. The latter is mounted in a block it, connected by links it with the head 1" of a shaft 71. The shaft 2' is arranged to have an endwise movement as well as a rapid rotary movement, the pulley 7;, by which it is driven, being mounted between projecting brackets c of the standard c and being engaged with the shaftto rotate the same, while permitting longitudinal movement of the shaft, by a longitudinal A le'ver Z is provided to support the shaft and effect the required longitudinal movement thereof. To limit the forward feed of the wire, rod, or bar to be cut, an adjustable stop m is supported in axial alinement with the fixed bushing a, being mounted in a slide n, so that the stop can be displaced laterally to permit the discharge of that portion of the wire, rod, or bar which has just been cut off and rests against the end of the stop. The slide it may be supported in suitable brackets 19 depending from the arm I), set-screws 19 being also provided to limit the movement of the slide with the step. A trough 0 may be secured to the arm e to discharge the cut-01f portion away from the line of the shaft 71. In the operation of the machine shown in these views, Figs. 1, 2, 3, and 4, bushings aand d, with a bore approximating to the diameter of the wire, rod, or bar to be out, having been placed in their respective holders, the wire, rod, or bar is fed through the bushings until its end rests against the stop m. The shaft 2' being now in its highest position, it is rotated rapidly and at the same time is gradually moved downward and away from the fixed bushing 04. When the shaft 1' is in its highest position, as clearly shown in Fig. 2, the pin g is axially in alinement with the shaft iand the bushings a, and d; but as the shaft is moved downward or away from the bushing a the action of the hinged block it and links h will throw the pin g out of alinement,

thereby also throwing the bushing d out ofalinement. The eccentricity of the bushing d with respect to the bushing a will thus be gradually increased, and as the shaft 2' is continuously rotated at a high speed the working edge of the bushing (I will act successively at different points about the periphery of the wire, rod, or bar to be cut and by reason of the increasing eccentricity will likewise act progressively until the wire, rod, or bar is finally severed through the cooperation ofthe two bushings. By reason of the fact that there is no angular displacement of the working edge of either bushing with respect to the wire, rod, or bar to be sheared and of the further fact that the point where the shearing action takes place travels with a rolling motion around the wire, rod, or bar to be cut in a path of grad ually-increasing eccentricity, progressively shearing the metal from different. points in succession, there is no material distortion of the ends of the wire, rod, or bar and no bur or fin, or at least no more bur or fin than may be completely removed by a slight tumbling or other similar finishing operation.

In the embodiment of the invention represented in Figs. 5, 6, and 7 one bushingp is adapted to rotate in fixed bearings q, while the other bushing r is mounted in bearings which are movable transversely with respect to the axis of the bushing 19. Such bearings 3 may be supported by the arms of a frame 1, pivoted eccentrically with respect to the bushing 19 and provided with an operating-handle u, and, if desired, with an adjustable stop 0). In this embodiment of the invention the wire, rod, or bar to be cut rotates with the bushings p and r and at substantially the same angular velocity. Therefore when the bushing 1' is shifted out of alinement with the bushingp and its eccentricity is continually increased the point of shearing of the metal progresses with a rolling movement with respect to the periphery of the wire, rod, or bar. The action of the two described forms of the machine is therefore the same, the relations of the bushings to each .other and to the wire, rod, or bar to be cutbeing substantially identical.

Other means than those shown for giving to the movable bushing the required movement with respect to the relatively fixed bushing whether both bushings and the wire rotate about their own axes or whether they do not will readily suggest themselves, and it will be understood that as to all of the details of construction and arrangement various changes maybe made without departing from the spirit of the invention.

I claim as my invention- 1.
